My grandma was an avid walleye fisherwoman.
Here is a tad of info about them.




Meaning of the name
The common name, "walleye," comes from the fact that their eyes, like those of cats, reflect light. This eyeshine is the result of a light-gathering layer in the eyes called the tapetum lucidum which allows the fish to see well in low-light conditions. In fact, many anglers look for walleyes at night since this is when most major feeding patterns occur. Their eyes also allow them to see well in turbid waters (stained or rough, breaking waters) which gives them an advantage over their prey. Thus, walleye anglers will commonly look for days and locations where there is a good "walleye chop" (i.e., rough water). This excellent vision also allows the fish to populate the deeper regions in a lake and can often be found in deeper water. This also means that since they live and spawn in mostly in shallow waters, they can see onto or near the shore for disturbances in the water such as humans.


[edit] Physical description

Walleye, Sander vitreusWalleyes grow to about 75 cm (30 in) in length, and weigh up to about 7 kg (15 lb). The maximum recorded size for the fish is 107 cm (42 in) in length and 11.3 kg (25 lb) in weight. The growth rate depends partly on where in their range they occur, with southern populations often growing faster and larger. In general, females grow larger than males. Walleyes may live for decades; the maximum recorded age is 29 years. In heavily fished populations, however, few walleye older than 5 or 6 years of age are encountered. In North America, where they are heavily prized, their typical size when caught is on the order of 18-25 inches, substantially below their potential size.

Walleyes are largely olive and gold in colour (hence the French common name: doré -- golden). The dorsal side of a walleye is olive, grading into a golden hue on the flanks. The olive/gold pattern is broken up by five darker saddles that extend to the upper sides. The colour shades to white on the belly. The mouth of a walleye is large and is armed with many sharp teeth. The first dorsal and anal fins are spinous as is the operculum. Walleyes are distinguished from their close cousin the sauger by the white colouration on the lower lobe of the caudal fin which is absent on the sauger. In addition, the two dorsals and the caudal fin of the sauger are marked with distinctive rows of black dots which are absent from or indistinct on the same fins of walleyes.





[edit] Reproduction
In most of the species' range, the majority of male walleyes mature at age 3 or 4. Females normally mature about a year later. Adults migrate to tributary streams in late winter or early spring to lay eggs over gravel and rock, although there are open water reef or shoal spawning strains as well. Some populations are known to spawn on sand or on vegetation. Spawning occurs at water temperatures of 6 to 10° C (43 to 50° F). A large female can lay up to 500,000 eggs and no care is given by the parents to the eggs or fry. The eggs are slightly adhesive and fall into spaces between rocks. The incubation period for the embryos is temperature-dependent but generally lasts from 12 to 30 days. After hatching, the free-swimming embryo spends about a week absorbing the relatively small amount of yolk. Once the yolk has been fully absorbed, the young walleye begins to feed on invertebrates such as fly larvæ and zooplankton. After 40 to 60 days, juvenile walleyes become piscivorous. Thenceforth, both juvenile and adult walleyes eat fish almost exclusively, frequently yellow perch or ciscoes, moving onto bars and shoals at night to feed. Walleye also feed heavily on crayfish, minnows, leeches, and earthworms.


[edit] As food
The walleye is often considered to have the best tasting flesh of any freshwater fish, and, consequently, is fished recreationally and commercially. Because of its nocturnal feeding habits, it is most easily caught at night using live minnows or lures that mimic small fish. Most commercial fisheries for walleye are situated in the Canadian waters of the Great Lakes, but there are other locations as well.

[edit] Fishing
Since walleyes have excellent visual acuity under low illumination levels, they tend to feed more extensively at dawn and dusk, on cloudy or overcast days and under choppy conditions when light penetration into the water column is disrupted. Although anglers interpret this as light avoidance, it is merely an expression of the walleye's competitive advantage over its prey under those conditions. Similarly, in darkly stained or turbid waters, walleye tend to feed throughout the day.

"Walleye chop" is a term used by walleye anglers for rough water typically with winds of 5 to 15 mph (7 to 24 km/h), and is one of the indicators for good walleye fishing due to the walleye's increased feeding activity during such conditions.

Because walleyes are popular with anglers, fishing for walleyes is regulated by most natural resource agencies. Management may include the use of quotas and length limits to ensure that populations are not over-exploited. As one example, in the state of Michigan, walleye of under 15" may not be legally kept.


[edit] Seasons
In springtime walleye will take almost any bait or lure, but may be more challenging to catch through the summer months. Fall often brings another peak of walleye feeding activity. Walleye are readily caught through the ice in winter, usually on jigs, jigging spoons or minnows.


[edit] Bait
Casting or trolling with spinners or minnow-imitating plugs is a good bet. Special worm harness rigs of spinners and beads are often trolled. Jigs, either traditional bucktails, or tipped with any of the modern plastics, a piece of worm or minnow are walleye angling favorites.

Live baits are often still-fished, drifted or trolled on slip-sinker or "bottom-bouncing" rigs. Excellent live bait choices are nightcrawlers, minnows, or leeches, all of which can be used on a jig.

When ice fishing walleye are caught jigging or on tip-ups. Tip-ups are generally set up with a dacron backing and a clear synthetic leader. For bait, the most common minnows are Fatheads and shiners. Size for bait is anywhere from 1 to 7 inches.


[edit] Minnesota

Large walleye statue at Mille Lacs in Garrison, MinnesotaThe walleye is the state fish of Minnesota. Its popularity with Minnesota residents means that the residents of that state consume more of the fish than in any other jurisdiction.

In 2004, it was revealed that some restaurants in the Minneapolis-St. Paul region had been substituting the less expensive, imported zander for the walleye indicated on the menu. Zander (pikeperch) is a closely-related species and is almost impossible to tell apart by taste, so the television station that did the exposé had to send samples of food for DNA testing. Though sold as "walleye," several samples were found to be zander, which is considered an illegal practice by the U.S. Food and Drug Administration. Zander is native to the Netherlands and Western Europe.
